Lateral sepals free. Lateral sepals with their bases 



adnate to the claw of the lip. 

 Lip flat or concave, without Lip with a more or less dis-

The first species of Piperia was originally described as 

 Spirantkes Unalaschensis Sprengel * and generally known as Habc- 

 naria Unalaschensis Wats. In the Kew Index this species is 

 referred to Hertmnium congcstum, a plant from northern India. 

 We have no specimen of the latter, but the identity is so unlikely 

 that I did not think of making a comparison when I visited Kew 

 last summer. P. Unalaschensis is no Hcrmijiium, however, for that 

 genus is distinguished by the total absence of a spur besides by 

 different structures of the column. Kraenzlin recognizes both Pla- 

 tanthera Unalaschensis and P. foctida. It is true that no one seems 



to know exactly what Spirantkes Unalaschensis Sprengel really was, 

 but I know of no plant except the present species, which agrees with 

 Sprengel' s short description. Kraenzlin placed P.

in the description he characterizes the latter as having the leaves 

 near the base. I cannot find any character on which to base a 

 segregation of two species. The publication of Platan tiara foctida 

 Geyer, is generally given as Hook. Journ. Bot. 7 : 376. 1855 ; 

 but there is no description, only the name and references to the lo- 

 cality where it was collected. The first real publication seems to 

 have been in King's Report, where Watson gives it as a synonym
